4GoalsDE-CIX Apollon will provide cutting edge interconnection on a 100GE level by choosing and implementing new infrastructure for both the optical layer and the switching layer.Apollon needs to support traffic and customer port growth for the next years. This includes scalable capacity in the core of up to 20Tbps in and 45 Tbps in 2018.Replace 1:1 redundancy in the core with n+1 redundancy.Keep local traffic local (switch and site).Core links must be 100GE to reduce the number of links, to better utilize bandwidth, and to be able to accommodate larger flows.Redundancy and multipathing on upper protocol layers.Need to address these issues one by one4-6 Years technologyMax. Link utilization 67% non-failure1 Flow is still tagged on one link.Upper protocol layers = MPLS

5Technology selectionWe need an optical platform and a switching platformGather informationMake a decision matrixOutput: Short list – 3 vendors for optical, 3 vendors for switchingDo extensive Lab tests with shorlisted partiesOne of the earliest decisions we made was to no longer use a passive optical platform,Why active instead of passive? No more special transceivers for switches needed, independend of form-factor of optics in switchesNo special support for colored optics in switch needed (tuning, forward error correction)Better optical monitoringDaniel spent the better part of a year arranging and doing lab tests with various vendors

7Technology selection: Switching Platform100G capableHigh port density (for 10G and 100G)3rd party transceivers possibleMultipathing (via MPLS)Port security at the edgeVLAN translations functionalityOne of the earliest decisions we made was to no longer use a passive optical platform,Daniel spent the better part of a year arranging and doing lab tests with various vendors

8Shortlist (Switching)One of the earliest decisions we made was to no longer use a passive optical platform,Daniel spent the better part of a year arranging and doing lab tests with various vendors

9Lab tests Up to 4 cores (2 minimum) 2 “new” access switches2 “old” access switches (to emulate migration scenario)Devices to emulate customers, 100G interconnections etc.Simulate all scenarios we could think ofSimulate the migration from old to newOne of the earliest decisions we made was to no longer use a passive optical platform,Daniel spent the better part of a year arranging and doing lab tests with various vendors

10Decision matrix All lab tests went into decision matrixSome blurred because we did not tell the vendors all the results

12Alcatel-Lucent 7950 XRS-20 Pro Con Ready for multi chassisBest implementation of required featuresExcellent hardware performanceMigration scenario possibleConOnly DC chassis (needs external rectifiers)No sflow (counter & samples; implementation necessary)Actually all platforms on the final shortlist were excellentWe finally decided for Alcatel, because very fast machine with extremely high port density and elegant implementation of all the features we needOnly cons we had were that the chassis is only DC, external rectifiers where ACNo sflow, IPFix insteas which is netflow, our software development guys need to put in some extra hours

13I promised you one marketing slide and that is itIt is awkward to say our new DE-CIX Adva and Alcatel Lucent platform so we gave it a nameAnd call it DE-CIX Apollon

15New Topology (snapshot)Getrennte Protection: Weniger Umschalten im Fehlerfall, keine Single point of Failure (der Umschalter)Protection: no „switching“ in case of failure – less single point of failure.Fibre protection = sending all on both fibres, receiving side selects which colors to receive where4 Cores, one per siteEdges at same sitesEach Edge is connected to each core1 core can fail without any impactSmaller sites we backhaul via DWDM systemOnce we have G ports on a site we put an edge switch there

16Migration Should be as painless for the customers as possible.No impact on daily opsDecision: Hire a dedicated project managerInvolve every departmentSales: Make customers and prospects aware of the upcoming migrationSupport: Handle customer requests before, during and after migrationEngineering: Do most of the actual workMarketing: Create Apollon branding, visual messaging, PR

17Migration (core) Migration steps:Add one core – will be done next weekFrom this point we could adding new edgesAdd all the remaining coresAdd one new core, take one old core outCore only new, all new edges inThen the fun begins – migrating all customersPlan not finalized – but we will migrated customers in as large chunks as possible

18Migration Steps Replace the core firstAdd one new core switchRemove one old core switchContinue until all cores are replaced and 4 new cores are activeReplace the edge switches one by oneLots of getting up early in the morning for customer support and engineeringSo, if customers think it is painful for them if their DE-CIX connection is being migrated please think about us

20Edge migration Connect new edge routers to the new coreKeep old edge switch runningMove customers fibre by fibreTest each customer after movingTry to keep individual downtime as short as possibleDuring each migration customer support will also be in the office to handle customer requests and questions.

21SummaryDE-CIX Apollon will provide a larger spectrum of Ethernet based interconnection services incl. Internet Exchange and Layer 2 data link functionality.Yes – there will be new products. We will keep you posted.DE-CIX is a one-stop shop for interconnection in an all Ethernet and all IP environment. All backed by industry leading SLAs.
